==General description==
The national heritage route, which is part of Sendero de Chile "Andes Centrales: Río Olivares Gran salto is a wonderful alternative for excursion lovers and is only 86 km. away from Santiago This route is now open to the public thanks to the funds and support of the Ministry of National Heritage, by means of their program Rutas Patrimoniales and CONAMAs (National Environmental Committee) program Sendero de Chile which allows a pedestrian access to the central mountain range, together with a written guide so travelers may enjoy their trip in a safe and well informed manner. The mountain trail is 27 km long, and requires at least four days of relaxed walking. This is recommended not only for security reasons but also to allow the traveler to have enough time to enjoy the natural scenery. Along the way one can also find suitable camping sites. During the excursion, the traveler will be rewarded with high-andean landscapes, beautiful rock formations, snowed peaks, evidence of ancient glaciers, waterfalls and the superb flight of the condor, in one of the pristine and purest valleys of this central mountain range.
==Location and access==

Olivares River-Gran Salto Patrimonial Road is located 86 km North-East Santiago, following road G- 25 Cajón del Maipo to the East, until Río Colorado crossing, taking then Road G- 345 Cajón del Colorado, to the North-East, until the location of El Alfalfal. Access to the road from the location of El Alfalfal is restricted at Gener S.A. control, having to request prior authorization to the Ministry of National Property. After recording entry at the control barrier, there are 7 km of double lane gravel road, parallel to Colorado River by the North, until reaching the first detour, taking alternative road to the left, the access to Olivares River basin. At this point starts a 12 km tour to the North, with a maximum 400 meter unevenness through a one lane road, along Olivares River border, and climbing a little slope until reaching Olivares River intake, corresponding to Gener S.A.s Olivares Sub-station. The road starts in a little detour to the left, just before arriving to intake facilities, specifically, at coordinates 394604 E / 6303570 N. Such road is bounded in the North by Gran Salto del Olivares, in the East by Olivares River, in the South by Olivares Intake, and in the West by Cordón del Cepo. Olivares River-Gran Salto Patrimonial Road is located North-East the pre-cordilleran location called El Alfalfal, district of San José de Maipo. It is a 27 km lineal road that recovers old paths used for mining, hunting, and cattle-raising activities, divided into four segments from Olivares River Sub-station, 2.050 meters above the sea level (Intake) to Gran Salto del Río Olivares, located 2.800 m.a.s.l. At least 4 days must be considered to complete the full round circuit, estimating days of 6 hours of continuous hiking, being also possible to ride a horse or mule, also considering in that case 4 days of 4 daily-hour riding. Summer and spring times are advisable in both cases for further security of the visitor. Alternatively, a cross country ski tour may be considered, specifically, in the first three segments at the beginning of spring time.
==Main atractive==
aspects of Olivares River-Gran Salto road are:
Plain Vegetation and Shrub Formation at Heights: It is possible to observe 4 plain formations of interesting configuration, which are connected to the presence of crystal water springs enabling development of vegetation and their use as supply and camping areas. These are: "Primera Vega", "Vega Larga", "Vega Casa de Piedra", and "Vega Honda". It is also possible to identify several species proper to elevated environments, many of them with therapeutic usage. Among the more commonly found flora in the road, we can mention Pingo Pingo, Junelia, Lengua de Gallina, Añañuca, Paihuén, Chacai, Rubilla, among others. Fauna: Condors is the most spectacular specie to observe. It can be seen both individually and in groups of 4 or more birds, flying close to the level of the ground, looking for preys, in particular, at "La Morrena" sector. It is also usual to have the presence of other birds: a variety of big finches, crown sparrow, small partridge, a variety of pheasant, and swallow, that can be seen in flatter sectors related to plains or stream and river beds. Geomorphy of the Landscape: Inside Olivares River basin, it is possible to observe a wide variety of geomorphy derived from plate tectonics, a complex faulting system, and erosive processes connected to quaternary glacial activity, specially referred, in the last case, to abrasion exercised by glacial bodies on the bedrock, the biggest glacial unit in the central Andean cordillera, and resulting from avalanche and snow melting phenomena, allowing to obtain a singular configuration of the main valley. We can highlight development of a number of outfall fans, among which such located in the East sector of El Bordón slope, in Primera Vega and Vega Honda, are the most important. Cascades: A number of cascades of very different sizes, that may be specially seen at the end of spring time and at the beginning of summer time, among which El Bordón stream, Los Castaños and Gran Salto falls of Olivares River may be highlighted for their panoramic scenario. Casa de Piedra (House of Stone): It is a lytic structure of both anthropologic and historic interest, without specific data on its origin; however, it is directly connected to activities carried out since remote times; first, camelidae hunting, and then, since the colony, occupation of summer pasture and as a traffic place connected to Las Pircas" or "Fraile crossing point.
